Core Lab announces a novel approach to deliver perforations across multiple intervals in a single
actuation, one trip system. This system runs on tubing and features a high level of performance
and reliability while offering time, material and equipment savings over traditional TCP, coil
tubing perforating and wireline perforating.
Applications:
Long interval perforating: PulseWave system eliminates the need for
blank spacer guns between perforating zones in either vertical or horizontal wells. Deployed on
tubing and using standard TCP firing head, it enables completion engineers to optimize reservoir
performance using under or overbalanced condition fit for reservoir. PulseWave’s substantial
cost-saving and environmental impact come from eliminating spacer guns and misfires associated
with human error during gun loading, reducing man-hours, rig time, and lowering explosive
residue.
Multi-interval perforating: PulseWave allows the perforating guns to be positioned and shot all
at once eliminating the need for time delay transfer components. Time Delay technology has many
inherent limitations including rig type that can be used for these type of operation and the 5
minute limit for repositioning of the guns between interval otherwise guns are shot off depth.
Refrac perforating: The PulseWave system can be configured into a single trip, multi-cluster
perforating string to create new perforations for re-stimulation of a previously producing well.
Often completion engineers do not want to isolate the old perforations and fractures from the
recompletion, so tubing is required to convey the guns horizontally. PulseWave is an ideal
technology to save coil tubing costs and time across multiple runs.
